|Stratoflex 311 straight flared fittings for 193 hose.|
Exactly what I was expecting. A perfect fit with Stratoflex 193-4 hose. Easy to install, no leaks.
Quality fittings used the 311-2D fittings on Stratoflex 193-2 hose. There do not appear to be any mandrels for 1/8 ID hose so a piece of nominal 1/8 rod was inserted into the hose. Then a 37 degree bulkhead fitting was screwed into the swivel hex nut so as to tighten against the 37 degree insert so all rotated together to reverse screw the hose into the insert.
